SPECIFICATION forming part of. Letters Patent N0. 544,593, dated August 13, 1895.

Application filed June '7, 1895- Serial No. 551,970. (No modelJ' seated inside a stove to burn liquid hydrocarbon as the fuel by reducing it to gaseous form by the heat generated from its combus tion in the heater.

The object of my invention is to provide a heater of the class referred to improved in matters of detail to facilitate and render more effective the operation of starting it to burn and generate gas from the hydrocarbon fuel fed to it and thereafter to permit more perfect regulation of the heater.

Referring to the accompanying drawings,

Fig. 2 is a plan view of the same; Fig. 3, a top-plan view of the upper deecting-plate detached from the mixing-chamber and with its two sections distended; Fig. 4, a bottom lplanview of the same; Fig. 5, a top plan View of the lower defiecting-plate; Fig. a bottom plan view of the same; Fig. 7, a plan view of the heater with the deflecting-plates removed; Fig. 8, a plan View of the sliding valve-plate employed in the mixingchamber and showing the means for working it; Fig. 9, a section taken at the'line 9 on Fig.` 12 and viewed in the direction of the arrow;v

Fig. 10, a section taken at the line 10 on Fig. 12 and viewed in the direction of the arrow; Fig. 11,a view like that presented in Fig. 10, but showing the slide-valve in the base of the heater open; and Fig. 12, a section taken at the line 12 on Fig. 7 and viewed in the direction of the arrow.

A denotes the shell of the heater, shown in its preferred oblong form with rounded ends and having a circumferential base-flange r cut away at :12,as indicated in Fig. 1. Inside the shell, which may be of cast metal,is formed, near its base, a circumferential flange q, to which the separately-formed bottom A is fastened by bolts t, as shown, and the space in the shell below the flange q affords a kindlingpan B. I provide in the bottom A two openings o and o', affording base air-inlets,` which are anged, as shown, about their inner ends, the flanges extendingv about to the plane of the flange q and affording a seat for aslidevalve C, guided in its movements by slots s, engaging studs s', thevalve being provided to control the air-supply and adapted in one position to cover both openings `0 and o and in its other position to uncover the opening o and coincide at an opening 02 provided in it with the opening o. In one side of the shell are door-openings p and n. adapted to be closed and opened by sliding doors p and n',

.each provided with a handle c, by which to manipulate it, the doors beingsupported in a suitable frame D, fastened tothe outer side of the shell. The Vdoor n is connected with he slide-valve O at a stud n2 thereon through he medium of a rod n3.

E is the mixing-chamber, seated on lugs w,

projecting from the inner sides of the shell.

The bottom Z of the mixing-chamber and the opposite sides thereof are arranged to aord the lateral longitudinal spaces or openings Z', and in the bottom are provided, to coincide with the air-inlet openings 0 0 in the base A, the downwardly-flaring flanged openings k and k. near the base of the mixing-chamber, ribsz' are cast on the bottom Z to extend transversely across and beyond it near its opposite ends, and the projecting ends of the ribs form, with ears t', extending from the sides of the mixing-chamber, jaws for holding the oil-supply pipe F, .which enters the shell A at one end of the mixing-chamber, extends along oney side of the latter and about its opposite end to the other side thereof, along which it extends nearly to the end at'which it is introduced, where it is bent downward and eX- tended back again underneath the openings k and'lt, at each of which it is provided with a perforation k2 and being closed at its extremity. I also show a steam-pipe G, entering the mixing-chamber at one end and eX- tending alongboth inner sides thereof, being connected at the farther end by a coupling IOO 8o To afford the spaces Z in the sides G', Fig. 7, and provided with perforations u. This pipe may be used at will by connection with a water-supply to admit water, which is vaporized in thepipe by the heat in the mixing-chamber and discharges into the latter as steam to mix with the products of combustion.

H is a valve-plate (see Fig. 8) supported on the ribs t' at the base of the mixing-chamber and having the extent of its movement limited by slots 7?. in its opposite ends engaging with studs 71.','extending upward from the ribs, the lugs and slots affording guides for the valve-plate, in which are provided openings 7a3 and 7a4 the same distance apart as the openings 7c and 7o. This valve-plate is provided with a side lug h2, projecting between the arms ot' a yoke 7;?, which extends inward from the sliding door p', whereby opening the door effects sliding of the valve-plate to cause it. to close the openings 7s and 7c by bringing its openings out ot' coincidence therewith, and closing the door brings the openings 7c3 and 7a4 in the valve-plate into coincidence with the openings 7o and 7c.

The mixing-chamber is surmounted by a plate E', having ribs t2 extending across its under side and at which it rests on the edges of the chamber', thus aiording side spaces or openings Z2, (see Figs. 9 and 12,) and in the plate E are provided openings 755 and 7a, coinciding with the openings 7c and 7a. The plate E is in turn surmounted by a plate E2, formed in two longitudinal sections g and g', having ribs Ai3 on their under sides to afford side openings 73 between them and the plate E', the section g' being stationary by engagement at a slotfin one end with a lug e on the upper side ot' the plate E and having a slotted tongue d in its opposite end to enter a recess f at the adjacent end of the section g, the slot in which tongue is guided by a lug e on rthe lower plate in the longitudinal movements of the section, the latter being further provided with an opening 707 and a recessf2 in its outer end to engage and be guided by a stud e2 on the plate E.

To start the burning of the heater, the door fn. is opened to cause the valve-plate C to cover and thus close both air-inlets o and o', and the door p should then be opened also to cause the valve-plate H to close both openings 7c and 7o to the openings 735 and 706 in the lower deilector-plate E. The supply of hydrocarbon oil is then opened to the pipe F, through which it flows and discharges at the perforations 7a2 upon the valve-plate C, which is provided with channels c,leading from depressions c', to direct the oil into the kindling-pan B. "When the desired quantity of the liquid fuel has been thus admitted, it is ignited, the heat partially Vaporizing the oil in the depending length of the pipe F and causing it to spurt out of the pcrforations 702 through the openings 7c and 7c. By keeping, during this period, the slide-valve I-I in position to cover the openings 7c and 7c' the oil thus spurted lcannot reach higher than the base of the mixing-chamber, whence `it flows out at the sides through the spaces or openings Z, adjacent to which are the lengths of the pipe F, and as the oil burns at these openings the generated heat is directed against the sections of pipe F, thereby heating the oil as it passes through the pipe, so that it is gasitied when it emerges from the perforations 7a2. When the heater has been thus started the door n is closed to open the airinlets o and 0 in the bottom of the heater, whereby all the air for promoting combustion is taken in at the base, an arrangement which prevents the roaring noise which ensues when thcair is fed from above the base, and the door p is closed to slide the valve-plate Vl-I into the position of bringing its openings 7a3 and 7a4 coincident with the openings 7c andk in the base of the mixing-chamber and the openings It and 756 inthe plate E', the platesection g being normally kept in the position to maintain its opening 707 out of coincidence with the opening 755. Thus the flame which shoots from the perforations 7a2 through the opening 7o and k2 enters the mixing-charnber and emerges therefrom through the side openings Z2 and Z3 after the products of -combustou have undergone thorough mixture in the mixing-chamber, and thereby a steady hot llame is generated to emerge throughout the length of the openings, extending along both sides of the plates E and E2.

When it is desired to employ the flame through the top of the plate F.2 the section g is moved to bring its opening k7 coincident with the opening 765, and this may also be done when it is desired to reduce the temperature inside the heater by directing a portion of the flame from impingement against the pipe F. The slide-valve H, moreover, maybe used to keep the heaterburning at a low heat, when it is desired to discontinue the use of the heater, without allowing it to go out entirely. This is done by opening the door p', which causes the slide-valve H to close the openings 7c and 7a and direct the products of combustion from a reduced supply of the liquid fuel, regulated accordingly, through the side openings L at the baseof the mixingchambcr against the adjacent sections of the pipe F to keep up sufficient heat for generating gas from the oil and maintaining the heater in condition forstarting up at any time.
